Climbing rose plant named ‘KORtrameilo’

ABSTRACT

A new and distinct variety of rose with long lasting, novel red flowers, and attractive foliage with excellent disease resistance. It exhibits moderately vigorous upright growth with abundant flowers. The new variety propagates well from cuttings and by grafting. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Latin name of genus and species: The botanical classification of the newrose plant is Rosa hybrida.

Variety denomination: The denomination of the new variety is‘KORtrameilo’.

The new variety of rose plant of the present invention originated from acontrolled crossing in a breeding program of two distinct parents duringthe summer of 2002. The crossing was between an un-named seedling, theseed parent, and another un-named seedling, the pollen parent, from thesame inventor.

The resulting seeds were planted during the following winter. Theresulting seedlings were evaluated and exhibited distinctive physicaland biological characteristics. The new rose plant was selected as asingle plant from the seedling beds due to its superior characteristicsand asexually propagated for further evaluation. This new anddistinctive rose variety is named ‘KORtrameilo’.

CROSS REFERENCES AND FEDERAL R&D STATEMENT

There are no cross referenced or related applications. This variety wasdeveloped without the aid of any research grant.

SUMMARY OF THE INVENTION

The new rose plant may be distinguished from its seed parent, anun-named seedling, by the following combination of characteristics:

-   -   1. ‘KORtrameilo’ has very double medium red flowers, whereas the        un-named seedling has semi-double dark red flowers.    -   2. ‘KORtrameilo’ has better disease resistance than the un-named        seedling.

The new rose plant may be distinguished from its pollen parent, anun-named seedling, by the following combination of characteristics:

-   -   1. ‘KORtrameilo’ has large flowers and a climbing growth habit,        whereas the un-named seedling has medium sized flowers and a        bushy growth habit.    -   2. ‘KORtrameilo’ has excellent disease resistance, whereas the        un-named seedling only has moderate disease resistance.

The objective of the hybridization was to create a new and distinct roseplant with unique qualities, such as:

-   -   1. Uniform growth and flowering;    -   2. Abundant attractive, recurrent flowers;    -   3. Attractive and abundant foliage; and    -   3. Resistance to diseases encountered in landscapes and gardens.

This combination of qualities is not present in prior rose cultivarsknown to the inventor. These objectives have been substantially achievedand in that distinguish ‘KORtrameilo’ from all other varieties of whichI am aware.

As part of a rose development program, Tim-Hermann Kordes germinatedseeds from the aforementioned hybridization and conducted evaluationsand observations on the resulting seedlings in a controlled environmentin Offenseth-Sparrieshoop, Germany. The resulting seedlings exhibiteddistinctive physical and biological characteristics. The new rose plant‘KORtrameilo’ was selected in May, 2003 from the seedling beds to beasexually propagated for further evaluation. The first asexualpropagation of ‘KORtrameilo’ was done by budding to seedling understocksin July, 2003 at the inventor's nursery in Offenseth-Sparrieshoop,Germany.

This initial and other subsequent propagations conducted in controlledenvironments demonstrate that ‘KORtrameilo’ reproduces true to type insuccessive generations of asexual reproduction.

DETAILED BOTANICAL DESCRIPTION

The following is a description of ‘KORtrameilo’, as observed growing inOctober, 2011 in a nursery in Jackson County, Oreg. on plants two yearsof age. Color references are made using The Royal Horticultural Society(London, England) Colour Chart, 2001 except where common terms of colorare used.

For a comparison, several physical characteristics of the rose variety‘KORgolgat’, a rose variety from the same inventor described andillustrated in U.S. Plant Pat. No. 17,376 and issued on Jan. 23, 2007are compared to ‘KORtrameilo’ in Chart 1.
